Seriously, though, the creativity that's being directed at making a mockery of the DMCA, while not "productive" in the strictest sense of the word, serves at least two important functions:

1. DMCArt, the more diverse and unrelated it becomes, has a greater liklihood of drawing attention to itself outside the already growing community who know about the DMCA and why it is evil.

At first, it was a widely distributed piece of illegal code but it had a limited audience and was a very abstract concept. Then somebody sang about it, and made it (while still impenitrable to the average American) a little catchy. I may even have memorized the song accidentally, making my brain illegal. Now people are creating new and more fascinating "interpretations" of DeCSS (almost none of them functionally equivalent to our hero, mind you) each possibly more interesting to another segment of society than the last. Soon, if we're lucky, you'll see CSSDescramble spraypainted on boxcars, and sold to unsuspecting patrons at galleries, and encoded in a pattern of bricks at the base of the latest high rise. That's when you'll know that the DMCA has finally been grepped by America. If people didn't direct their creative juices at this, it would be an unapproachable "Washington thing" (like "insurance,", right Mr. President?).

2. It keeps people like me from rotting their brain with television for a while, and instead learning more about our craft. That prime number guy likes numbers, so he sits himself down and keeps his tool sharp by finding his own way to say "fuck you" to the DMCA. The guy who wrote the song has a band, and it damn well served a purpose for him beyond mocking the movie studio cabal. So it's not just a noble, necessary thing to criticize the DMCA with art, it's a selfish thing.

And those are the best things to do of all.

This encoding is no different from any other decoding: It changes information from one representation to another. This is not new - only this particular encoding is new, but the idea of encoding is certainly not new.

Ok, the rest here is speculation:

Clearly, gzipping some piece of software does not change the licensing of that software. So, what if I work with numerical simulations and purely by chance my plasma physics data set can be gunzipped into a full distribution of [insert some proprietary software here] ?

I guess that would be ok, because clearly this happened by chance and I never intended to actually gunzip my data set.

Likewise, if your key-exchange code by chance generates a prime that just happens to encode some piece of IP, it should be hard for anyone to sue you.

On the other hand, encoding the "original" for the purpose of distributing it in some alternative representation has always been illegal. gzipping IP doesn't make it legal, neither does encoding it into a prime number after it's gzipped.

But this is a funny problem ! It puts a new angle on "Intellectual Poverty".

But using some prime->original decoder is no different from say, gunzip. It's decoding of information in on form back to it's "original" form.

So no, making copies of Win2K is not legal wether it's gzipped or encoded into a prime.

And distributing DeCSS as a prime number (or gzipped) doesn't change the legality either.

Subtracting 1 from the number then distributing that number just adds another layer on your decoder, it doesn't change what you're doing. gzipping something twice doesn't remove the licensing restrictions either.

However, this is interesting because it puts a new angle on the flawed notion of "Intellectual Property" (or, Intellectual Poverty as I like to call it, because that must be what we suffer from if we restrict other's access to ideas that are indeed just mathematics in some form or another).

My question for a lawyer is this; does Microsoft have legal copyright on some numbers?I'm not a lawyer, but the answer is obviously yes: every piece of Microsoft software can be encoded as a (usually multimillion digit) number. Sending that number to someone else would violate copyright law.

If so, do they also own every number that can be derived mathematically from them?No; just because they have a copyright on n doesn't mean they own n - n = 0 or n / n = 1, Onion article [theonion.com] to the contrary.

You might say they own every number that

On the other hand, you could distribute a file containing the first 10^1500 integers, and as long as you didn't also distribute a way of discerning which integers were copyrighted your act should be useless but legal.Of course, I'm one of those folks who thinks that the War on Drugs and DMCA are unconstitutional, so if you're actually considering brushing up against the law you should ignore everything I say.

Beware of two things you're doing here: you're imagining that primes, Pi, and e are all sequences of "random" digits. They certainly look that way, but it isn't true, and some of that non-randomness may, for example, prevent a particular number from ever appearing in the digit sequence. Secondly, you're trying to make a mathematical argument from "common sense" rather than from axioms and logic. That doesn't work as often as you'd wish it would; common sense sucks.

Where 1 is a prime or not is largely a matter of contention. But you certainly cannot call it a composite number, for then all other prime numbers would have to be composite as well.

In retrospect, it was only a matter of time 'till something like this happened. Programs are long numbers, and through this method you can now make any program a prime number.

The idea that all IP is just "numbers" and can't be owned is a fallacy. Anything in the universe can be hashed to a numerical representation. My car has a number, and I most certainly can own it. To suggest otherwise is to advocate a communist system.

If you really believe that all IP is just a number, you are welcome to develop software by spewing bignums into a buffer and executing them to see whether or not they are useful.

That's probably not entirely clear, so I will explain what I mean by calling your number a construct. The algorithm you describe does not really generate a number. It generates a string of digits. If you convert the number corresponding to this string of digits to a different base, your pattern vanishes. Thus it is not really a natural pattern, but a coincidence created by working backwards, kind of like the images in the gallery of DeCSS decoders that just happen to have the gzipped code embedded in them. You have created a very interesting coincidence, but it's like saying that because you can build a Pentium III from elements found in nature, that Pentium IIIs are naturally occurring. Even Douglas Adams would grimace at that one.

## Re:Windows 2000 encoded to a single number! (Score:3)

It isn't even remotely interesting. There are a *lot* of prime numbers. About one on 3000, for a 1400 digits number.

Considering how easy it is to build valid variation of a gzippped file, it is a one banana thing.

Even if gzip would not accept any variation (ie: if a source file could give only one gzip file, and if any alteration would produce an error at output), then modify the C source file would be just too easy (put a '/*n*/' at the begining, and compress for n incrementing from zero. Would take about 1500 try), unless gzi pformat could never give you a prime number (ie: always finished with a binary '0')

Now, what is the size of w2k source code ? 1 Gygabyte ? There are prime numbers about every few billions in that range. By messing with 4 bytes (!) of the source, you can have resonable expectation that you can make the result a prime number (if windows source code ends with a binary '1', of course).

Open Source Transcendental ConstantIn a revelation that could rock the foundations of science, a researcher in Pennsylvania has discovered that the digits of the transcendental constant PI encode a version of the Linux kernel. "I can't believe it," the researcher, Neil Hoffman, exclaimed. "And yet, here I am staring at what appears to be the source code for Linux kernel 5.0.0. Needless to say, my whole world-view has changed..."

Hoffman made the discovery accidentally. "I was trying to write a more efficient algorithm in C to calculate individual digits of PI. However, my relative lack of programming experience, combined with C's highly obfuscated syntax, led me to the discovery. Instead of calculating each digit and returning it as an int, my program was (for some reason I still haven't been able to figure out) converting it to its ASCII equivalent and returning it as a char."

"Then it hit me. What if some kind of secret messages, encoded in ASCII, was stored in the digits of PI? I set to work on the problem, and after several months of toil, have discovered the awesome truth. My algorithm, which applies several dozen conversions and manipulations of each digit of PI, spits out plain vanilla ASCII characters that happen to form the source code for the Linux kernel."

"I tried to compile the source code, but gcc choked on it. Apparently a later version of gcc is needed to compile the Linux 5.0.0 source code. It's too bad the code for gcc isn't encoded in another transcendental constant. Or is it? I wonder what would happen if I fed e through my algorithm..."

Many scientists are skeptical about Hoffman's discovery. One mathematician who has memorized the digits of PI to 10,000 places said, "This is the kind of nonsense one would expect to find in a tabloid such as the National Mathematics Enquirer. Or a nerd humor site. Hoffman's discovery' is obviously a hoax designed to secure government research grants."

Another scientist Segfault contacted said, "Hoffman's claim is filled with holes large enough to push Windows 95 through. Apply a little critical thinking and look at all the inconsistencies and problems with Hoffman's discovery'. ASCII is an arbitrary code. Why not EBCDIC? Also, the base 10 number system, which his PI-to-ASCII scheme is based on, is arbitrary. Why not binary numbers? Oh, and then there's the biggie: PI is infinitely long. The Linux source code is not (Windows NT, on the other hand...). Explain that, PI Boy!"

Hoffman will formally present his findings to the scientific community on March 14th at the Annual PI Day Conference and Exposition in Chicago. One conference attendee said, "Usually the PI Day expo is pretty boring, with some asinine workshops about 'The History of PI' and Teaching Techniques to Make Learning About PI More Fun for Remedial High School Students'. However, with the unfolding brouhaha surrounding the Linux-PI connection, this could be a very interesting convention. Then again, there's going to be several hundred mathematicians from around the world in attendance. It might not be that exciting after all."

In a related matter, Segfault has received an unconfirmed report that a region of the standard Mandelbrot fractal contains what appear to be the words "LINUS TORVALDS WAS HERE". In addition, the words "TRANSMETA: THIS SECRET MESSAGE IS NOT HERE YET" supposedly appear within the depths of the Julia Set.

Linus Torvalds and Benoit Mandelbrot were unavailable for comment at press time.

Your recipient has the message and all you transferred was two completely unrelated numbers.You seem to have an odd definition of "unrelated". "Extract a sequence of pi starting at position X and continuing to position Y." is a fairly simple function, that can be defined as a decryption scheme. The numbers you find into that scheme are your encoded message and the result is your message. Just because your formula uses pi doesn't make your input unrelated to your output.

On the other hand, XOR

doesallow for some confusion. Imagine I take a purely random file (based off of measuring radioactive decay or some such) and then XOR it with DeCSS. Now I've got my random file and my encrypted DeCSS -- the catch is that there's no way to tell which is which. If I've got both files, I can XOR them and get DeCSS, but otherwisebothfiles look like random noise andbothfiles are treated "equally" by the decryption process.To make things even more interesting, imagine two people, named Bob and Ted, who have online collections of files with random numbers in them. Now let's say Ted's a bit of a free speech advocate. So he takes a copy of DeCSS, XORs it with one of Bob's random number files, and posts it to his site as a collection of random numbers. How do you prove that it's Ted who's hosting the copy of DeCSS and not Bob? What if you force Bob to remove his set of random numbers, when someone else had used that set as an XOR decryption key for something else? What if that person had both the encrypted and unencrypted versions available (say, as a demonstration of using XOR to encrypt a file)? Using the encrypted and unencrypted versions for the third party, you could recreate Bob's (removed) key. Then you could use that key to decrypt Ted's encrypted DeCSS.
